Weather in September
Temperature
On the advent of September, Petal's average high-temperature exhibits a minor adjustment to a still hot 87.8°F (31°C) from August's 91.8°F (33.2°C). Throughout September, an average low-temperature of 68°F (20°C) is expected in Petal.Heat index
The heat index value during September is computed to be a scorching 104°F (40°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
